Media Free Silencers
We have developed a line of media free silencers that are designed to provide excellent broadband attenuation without the use of fiberfill media. The absence of fiberfill media eliminates the concern of fiber erosion or microbial growth in the air stream. The moderate pressure loss makes these silencers suitable for all sensitive applications in systems operating at higher velocities. Sensitive applications requiring a contaminate free environment include hospitals, pharmaceuticals, electronics and clean rooms. We also offer a media free fume hood exhaust systems specifically designed to eliminate the environmental dangers associated with chemical fume absorption.
304 and 316 stainless steel are available in both standard grade or "L" grade (low carbon) with either a No. 2b finish (standard mill finish) or a No. 4 finish (standard polish). 304 or 316 stainless steel with a No. 4 finish is available on a special order basis only and minimum quantity requirements may apply.
